Video Distance Chart
Understanding Distance Limitations
To assist with system design, tables have been developed based on signal loss recommendations for different video formats as outlined by SMPTE. These tables are regularly updated to include new signal formats and cable variations as technology progresses.
However, it’s important to recognize a key consideration when using these tables: "The bit error rate (BER) can vary significantly as transmission distances approach the calculated limits. BER is influenced by receiver design and the specific characteristics of the coaxial cable used. It’s always advisable to consult with equipment manufacturers to confirm their recommended maximum transmission distances."
Some engineers design systems that push coaxial cable to its maximum distance limitations, while others incorporate a safety margin to ensure long-term reliability.
